Asthma is a chronic respiratory condition affecting millions worldwide, including a significant population in Bangalore. Identifying asthma and monitoring lung function is crucial for effective management. A Pulmonary Function Test (PFT) is a key diagnostic tool that helps evaluate lung health, detect asthma, and guide treatment decisions. If you’re in Bangalore and experiencing respiratory symptoms, a Pulmonary Function Test for Asthma can provide valuable insights.
This article covers everything you need to know about PFTs, including types, procedures, costs, and where to get tested in Bangalore.
What is a Pulmonary Function Test (PFT)?
A Pulmonary Function Test (PFT) is a group of non-invasive tests that assess lung function by measuring airflow, lung volume, and gas exchange. These tests are essential for diagnosing asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders.
Key Functions of PFTs:
- Determine lung capacity and airflow restriction
- Detect asthma, COPD, and other lung diseases
- Evaluate the effectiveness of asthma treatments
- Monitor disease progression
Types of Pulmonary Function Tests for Asthma
- Spirometry
- Measures how much air you inhale, exhale, and how quickly you breathe out
- Helps diagnose obstructive lung conditions like asthma
- Peak Expiratory Flow (PEF) Test
- Measures the fastest speed at which you can exhale air
- Useful for tracking asthma severity and treatment effectiveness
- Methacholine Challenge Test
- Involves inhaling methacholine to see if it triggers airway constriction
- Helps diagnose asthma in borderline cases
- Lung Volume Measurement
- Determines the total lung capacity and residual volume
- Useful for differentiating asthma from restrictive lung diseases
- Gas Diffusion Test
- Evaluates how well the lungs transfer oxygen and carbon dioxide
- Used when additional testing is needed for severe asthma
Who Needs a Pulmonary Function Test for Asthma?
You may need a PFT if you experience:
- Persistent cough, wheezing, or shortness of breath
- Chest tightness or frequent respiratory infections
- Difficulty breathing during exercise
- Family history of asthma or other lung diseases
- Need for routine asthma monitoring

No, a PFT is non-invasive and painless. You may feel slightly breathless during certain tests, but there are no major side effects.
2. How accurate is a PFT for asthma diagnosis?
PFTs are highly accurate in detecting airflow obstruction and asthma-related lung issues. However, additional tests like the methacholine challenge may be required for borderline cases.
3. Can children undergo a Pulmonary Function Test for Asthma?
Yes, children above the age of 5 can undergo spirometry and other PFTs with proper guidance.
4. Do I need a doctor’s prescription for a PFT?
Most diagnostic centers require a doctor’s referral, but some allow walk-in testing.
